' tions in the extent of different sound rec my copending applicationSerial 175,082,

following is a specification, reference being had to the accompanyingdrawings.

My invention relates to. sound recording and reproducing machines,including gramophones and graphophones; and particularly feed mechanismfor sound boxes of such machines adjustable to automatically repeattheir cooperation with a given sound record, at the will ofthe operator.

As hereinafterdescribed, my invention 'is specifically adapted for suchmachines arranged to cobperate with fiat disk records,

and having sound conducting tubular arms or horns which 'move with thesound boxes,

uponsuch movement, to an adjustably predeterminedextent. I find. itconvenient to illustrate and de} scribe myinvention herein inconnectionfeed mechanism shown in with a gramophone of the type knowncommercially as a Victor talking machine. However, it is to beunderstood that I do not desire t'o limit myself to such aspecificembodiment of my invention, which includes the various novel featuresof" construction and arrangement hereinafter more definitely The twoembodiments of my invention" chosen for illustration herein, thoughspecifically-different in their details of con- I struction, each.include means to variabl predetermine the initial and terminal posi-'tions of respective sound boxes with referwith a single rotarycamconstructed and "ar' ranged to automatically lift-the sound box fromcooperative relation with the record when it reaches a variablypredetermined terminal position, and to then return thesound box toitsinitial position and again lower t into-cooperative relation with the,record; said-cam having the capacity to shift said sound box throughoutthe maximumirange of its movement by frictional engagement of acam platecarried with the filed June 16, 1917, for Letters Patent of the PatentedApr. 22, 1191M.

Referring to the shown in Figs. I'to VII- inclusive;-as=shown in Figs. Iand II, the casing 1 incloses a gramophone including. the record turntable" 2 arranged --to be turned by the motor 3 which is mounted uponthe under sideof the casing top 4 which is detachably rigidly secured insaid casing 1. The sound box 5 includesa vibratory diaphragm, andcarries the stylus 6, arranged to traverse a groove in the record 8 onsaid turn table 2 and automatically shift said box toward the axis ofsaid table. Said sound box 5 is attached to the tubular goose neck 10mounted-to turn upon the axis 11 in the cross tube 12 in thetubulartonearm 13' which thuscarries said sound box 5.- Said tone arm 13is mounted to swing, in a horizontal plane, upon its vertical pivot pin14 which is ournaled in .the bearing 15, rigidly connected withsaid 22which registers with the cam-24, whichhas the capacity to shift saidsound box 5 throughout-the maximum range of its move-' ment, away fromthe axis of said turntable 2, by frlctional engagement with said arcualarm. I

As shown in detail in Figs. IIIto VI incluslve; said cam. 24 is rigidlyconnected with the shaft 26 which is mounted to reciprocate in the frame27 which is rigidly connected with said casing top 4. Said shaft 26 alsohas rigidly connected therewith the gear 28 whereby said shaft 26 andcam'24 are turned, when said gear is engaged with the driving gear 30upon the vertical driving shaft 31, which, as shown in Fig. II, isjournaled in said frame 27 and in the frame 32 and carr1es, near itslower end, the gear 34 engaging the gear 35 on the shaft 36 carrying thegear 37 engaging the gear 38 on the shaft form of my invention Suchmovement is automatically ef-' having the gear 40 engaging the'gear 42of said motor 3; so that said motor, which rotates the turn table 2,also operates my improved feed mechanlsm.

Said gear'28, of the'feed mechanism, is automatically shifted both toand from en- --gagement with said gear 30 by the single spring 45,coiiperating with the mechanism shown in-detail in Figs. III to- VIinclusive.

' Said spring 45 is attached atone end to the tappet 47, by the screw 48which secures said tappet upon the slide ban'49, which is mounted toreciprocate in said frame 27. The opposite end of said spring 45 isattached to the lever 51 which is fulcrumed at 52 upon said frame 27 andhas the. stud v54 at its opposite end engaging the annular groove 55 inthe sleeve 56 which 1sv -rigidly secured to said shaft 26 by the screw57. Said slidebar 49 registers-with the crown cam 59, carried by saidgear 28 on the shaft 26 ;"so that rotation of said gear- 28, in thedirection of the arrow marked thereon in Fig. III, thrusts said slidebar 49 into the position shown in Figs. III and IV, in which said spring45 is stretched, and, by its tension shifts said rigidly connected cam24, shaft 26,- and gear 28, to the'idle position shown in Figs. I to Vinclusive. Said slide bar 49 is detained in that position by thetripping lever 54, which is fulcrumed "at 55 on said frame 27 and hasits hooked.

end engaging said tappet 47, as'shown in Fig. III, under pressure of thespring 58 which is carried by said lever 54 and bears upon said tappet47; In such idle'position of the feed mechanism, the stud 60 on saidframe 27 extends in the notch 61 in said sleeve 56, asshown in Fig. IV;thus insuring that said cam 24 shall be in the rotary posi tion shown inFig. V, when the gear 28 is disengaged from the gear 30 by the action ofsaid spring 45, and further insuring that it shall not be accidentallyturned while said gears are thus disengaged. Said spring 45 operates toshift the clutch gear 28 in both directions, solely by tension of saidspring, and in both instances effects a change in the angularrelation-of the lever 51 with reference to the plane which is com mon tothe axes of said shaft 26 and said slide 'bar 49; When said spring 45has its end which is attached to the tappet block 47 held stationary,'byengagement of said blockwith the detent 54, as shown in Fig. III;

' said spring tends to increase the angle between the upper edge of saidlever 51 and said plane,.thus tending to shift said shaft' 26 and itsappurtenances away from the 'dr ivmggear 30. However, when that end ofsaid spring 45 is free to move, byrelease of said detent; 54 fromsaidtappet 47, as indicated in Fig. VI, said spring tends to decrease theangle aforesaid. by drawing said tappet block 47 and said lever 51closer tot am gether and, because said lever 51 is anchored to the frame27 at its fulcrum 52, the tension of said spring then effects movementofsa1d shaft 26 and its gear 28 toward said gear 30,

to engage said gears.

It may be observed, that in said idle position of the gear shiftingmechanism above v described, the slide bar 49 has been released by thecam 59 which stretched saidspring '45 to efiect the disengagement ofsa1d gear 28 from the gear 30, and that said spring 45 is therefore freeto, contract and shift said cam 24, shaft 26, and gear 28 in theopposite direction, when said tappet 47 is released by thedetentlever54. lease is conveniently effected by providmg said lever 54 with theupturned arm 63 in position to encounter a stop member carriedby saidtone arm 13. As it is the purpose of my-i nvention to shift said soundbox from its terminal position upon any record, to its proper initialposition with respect to such 'record; it is important to note thatthere is considerable'variation in the radial position of the initialand terminal portions of sound record grooves in records of the samenominal size and, therefore, I provide stop .mechanism which isadjustably var1able to predetermine the initial and terminal-positionsof said sound box with reference to any given -record. Forinstance,i.the adjustable stop member 64 ShOWIliiIh Figs. III and V is agear rack carried by said lever 18; said rack being mounted toreciprocate, horizontally, in'i the slide bearing 65 on the dialplate 67which is conveniently riveted to the arm 22 "of said lever 18 asindicated at 68 in Figs. III and V. As shown in Figs. III,

cludes the base plate 79 which is rigidly connected with the casing top4, by screws 80, and has thearcual slide plate 81longitudinallyeadjusta'ble thereon, said plate 81 having a palr offlanges 82 embracing said base plate 79, and having a slot 83 throughwhich the clamp screw 84 extendsin engagement with said base plate 79.When said screw '84 is. loosened;- bymanually turning its Inilled'head85, saidplate 81 may be longitudinally adjusted by itshandle 86'tn.pre-. sent its rubber covered end 87 in position to encounter thependent arm 88' of said bracket and thus predetermine the initialposition of the sound box 5, with reference to any given record 8,carried by said turntable 2-.

Thereupon, said initial stopmechanism member 81 '18 adjusted to contact with said arm, 88 carried iby the tone arm 13 and thus insure that when the latter is returned, itwill be stopped in the correct'initial position with-respect to thatrecord. Said sound box 5 lsthen convolution 9 of the sound groove insaid record, and the terminal stop' mechanism shifted toward the axis ofthe turn table 2;" until the stylus 6 registers with the terminal.

member 64 is-then adjusted,- by rotation of y the milled head 71, untilthe tripping lever 54 is released from the tappet 4 Thereupon, saidsound box 5 is automatlcally returned to the aforesaid initial position,by

the operation of the feed mechanism above contemplated. That is to say;when said detent lever 54 is thus released, sa1d spring 45 contracts andshifts the shaft 26 until the as Shown in Fig. VI," thus withdrawing thesleeve 56 from its engagement with the stud 60 and permitting said cam'shaft26 to be rotated by the motor 3. Said cam 24 is thus gear 28thereon engages the driving'gear-30,

turned in the direction of the arrow marked thereon in Fig. V, thusraising the arcual end of said lever 18 and correspondingly depressingits opposite end in engagement with the lever 17 carried bythe soundibox5, and

.thus lifting the latter and the-stylus 6 from coiiperative relationwith said record. The continued turmngmovementof sa1d cam 24," I

Dur

ing the last quarter revolution of said cam 24, the crown cam 59 thruststhe slide bar 49 i to restorelthe spring 45 to its stretched positionshown inFigs. III and IV, but said spring is not effective to releasethe gear 28 from the gear 30 until thenotch 61:.in the stud 60 on theframe 27, III andIV.

p sleeve 56 is presented in registry With'the. 1

as shown in Figs 2 Only a few seconds intermission is required for theautomatic return of the sound box from its terminal to its initialposition as above contemplated, and the playing! operation may beautomatically repeated un-' til the mechanism is stopped by theoperator.

As shown in Fig. XIII, I prefer to provide 1 80 said tone arm bracket 20with the projection 21 upon which said sound box 5 may be rested in idleposition; thus permitting noiseless operation of the feed mechanism, andfacilitating its adjustment.

The initial stop mechanism shown in Figs. I and III has the slot 83 inthe slide bar 84 of such length as to permit the adjustment of themechanism to play records of all of the different diameters found incommerce. An initial stop device, having the same capacity but morecompactly arranged, is shown in Figs. VIII and IX, wherein 90 is a baseplate fixed upon the casing top 4: by screws 91 and having the arcualslot 92 for engagement with the studs 93 and 9 1 which,

are fixed in the stop slide bar 96. Said stud 941 extends above saidstop bar 96 to form the handle 97 by which said bar may be adjusted, andthe spring -98, which is compressed between the head of said stud 94 andthe under surface of said base plate 90 frictionally engages them so asto prevent acci-' dental displacement of said bar. Said bar is providedwith the index pointer 100 whereby it may be precisely set withreference to the graduations 101.

Of course, if the machine is to be restricted to the operation ofrecords of a less i the slot 106 through which the screw stud 108extends from said base plate 102, in engagement with the milled nut 109by which said stop member 105 may be secured in adjusted. position. Saidstop member 105 is conveniently provided with the gear rack 110, engagedby the gear sector 111 whichis fulcrumed upon the stud 112 and has theindex pointer 113, provided with the handle 114by which it may beprecisely adjusted with reference to the graduations 115 on the scaleplate 116.

In Figs. XI and XII, I show an initial stop mechanism including elementssimilar to the elements of the terminal sto mechanism shown in Figs. IIIand V an including the dial base plate 118, which is rigidly securedupon the casing top 1, by screws 119, in such position that its stopmember 120 may encounter said arm 88 pendent from the bracket 20 on thetone arm 13. Said stop member 120 is a gear rack slide bar mounted toreciprocate in the bearin 121 on the back of said base plate 118 anengaged by the gear 123 carried by the shaft 121 having the milled knob125 carrying the index pointer 126 adapted to traverse the circularseries of graduations 127 on said plate 118. Acci dental movement ofsaid stop member 120 is prevented by the spring 128 compressed betweensaid plate 118 and gear 123 and frictionally engaging them.

The gramophone indicated in Figs. I and III is of the large type mountedina casing which rests upon the floor. I have found it desirable to morecompactly arrange the gear shifting mechanism for machines of thesmaller type, and show in Fig. XIV such a modification of-my invention,which Was designed for use in the Victor No. IX machine, in which thecasing is smallerthan the casing 1 above contemplated and adapted torest upon a table or other similar support. In said figure; the frame130 has its base flange 131 resting upon the casing top 4 and itsopposite end supported by the bearing 15 at the upper end of theamplifyin horn 16, indicated in Fig. II. The cam sha 138 is mounted toreciprocate in said frame 130, and carries the cam 131 adjoinin thesleeve 135 whereby said shaft may be shlfted', by mechanism constructedand arranged as above described, including a spring 15. This form of myinvention may not only be set closer to the axis of rotation of the tonearm 13, but is of less extent with reference to the axis of the camshaft than the form of my invention shown in Figs. I to VI inclusive andis .thus adapted for a machine of smaller dimensions than is shown inFigs. I and II. Moreover, the stud 137 on said frame 130 is adapted todirectly engage the notch 138 in said cam 134 when the gear 28 isshifted to idle position, as shown in Fig. XIV, and thus Preventaccidental displacement of said cam'until said gear is reengaged withthe gear 30.

It is to be understood that such an embodiment of my invention asindicated in Fig. XIV may be substituted for the larger gear shiftingmechanism shown in Figs. I to VI inclusive, to cooperate with the lever18 and other elements shown in the latter fig ures.

I do not desire to limit myself to the pre cise details of constructionand arrangement of my invention herein set forth as it is obvious thatvarious modifications maybe made therein without departin from theessential features thereof as de ned in the appended claims.
